Porsche Cayenne GTS 958.2 vs Porsche Cayman S PDK 987: which is truly faster?

Off the line, the Cayman S PDK hits 100 km/h in 4.67 s versus 4.92 s for the Cayenne GTS. The 0.25 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Cayman S PDK is doing 151 km/h against 141 km/h for the Cayenne GTS. The gap is 0.20 s. The gap remains stable from the start.

At 400 metres standing start, the Cayman S PDK crosses the line in 12.60 s versus 13.11 s. The 0.51 s gap represents roughly 25 m of track - two to three car lengths.

Past 400 metres, the Cayman S PDK continues to build its lead. At 600 metres, it runs at 212 km/h versus 195 km/h. At 1,000 metres, the Cayman S PDK finishes in 22.56 s versus 23.91 s, with a 1.35 s lead.

The Cayenne GTS features all-wheel drive (AWD) against the Cayman S PDK’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Electronically capped at 262 km/h, the Cayenne GTS never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.80 kg/hp vs 4.24 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.37 seconds. The 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
